Description including Unit Aims
This unit builds on knowledge and skills learned in the Mineralogy and Petrology unit in year 2 of the Geology programmes (EASC20035). The following topics will be explored:
- Melting of crust and mantle rocks
- Crystallisation of magmas, including kinetics
- Volatile solubility in silicate melts
- Application of ternary phase diagrams to igneous petrology
- Methods of constraining magmatic variables, such as pressure, temperature, redox state
- Case studies of selected volcanoes to illustrate crustal magmatic processes
- Links between petrology and volcano monitoring
- Application of thermodynamics to igneous processes
- Experimental petrology
- Microbeam analysis
Intended Learning Outcomes
On successful completion of the unit, you will be able to:
- Understand melting and crystallisation processes with the Earth’s crust and mantle
- Understand the controls on trace element distribution within the Earth
- Understand the controls of volcanic gas chemistry
- Determine magmatic intensive parameters using mineral and glass chemistry
- Be aware of the different types of experimental and analytical equipment used in petrology
- Link magmatic processes to the volcanic and plutonic rocks they produce
- Use complex phase diagrams to interpret igneous rocks and their textures
- Use thermodynamic data to describe igneous processes
- Understand the links between magmatism and mineralisation
- Describe the eruptive history of several case study volcanoes
- Understand the importance of heat in driving crustal magmatism
Teaching Information
